Difference Between AFIB and CHF

There exist different organs in the human body. These organs conduct several roles. Different organs play different roles in the human body. A human can function properly when all the organs are in good condition and are in good health.

May it is diet or lifestyle, one must stay healthy to stay away from diseases, disorders, and any sort of illness. However, there are several disorders associated with the human heart if it doesn’t function properly or if it is not in a good state.


The main difference between AFIB or atrial fibrillation and CHF or Congestive heart failure is the causes of the respective disorders. Atrial fibrillation is caused due to the occurrence of problems in the heart valves. On the other hand, congestive heart failure is caused due to a heart attack or any other disease associated with the coronary artery.

It is caused due to several reasons, but mostly it is caused due to high blood pressure and problems associated with the heart valves. It can be treated and cured by medication. There are other treatment options as well.

There are several diagnoses options by which one can understand if they have CHF or not. However, ECG and/ or a chest X-ray is some of the common diagnoses options.

Parameters of ComparisonAFIBCHF
Full formsAtrial fibrillation Congestive heart failure
Meaning/ DefinitionThe disorder in which the atria present in the human heart lacks the rhythm or it beats irregularly is known as atrial fibrillation or AFIB.The disorder in which the pumping of the heart is not done well and due to which the fluids in the body are amassed is known as congestive heart failure or CHF.
Risk factorsPeople belonging to the age group of 60 years and above are more likely to have this disorder, people with blood pressure issues, people with coronary artery disease, etc.People who have a family history of congestive heart failure, people who are diabetic, people who have coronary artery disease, etc.
What happensThe rhythm of the atria is irregular.The fluids get collected due to the improper pumping of the heart.
SymptomsShortening of breath, difficulty in doing activities like exercising, feeling light in the head, etc.Swelling is observed in the ankles, fatigue, and difficulty in breathing.

What is AFIB?

AFIB or Atrial fibrillation is a heart disorder which when it occurs, causes irregularities in the rhythm of the atrial. It is one of the most severe heart disorders, and it is most likely to be diagnosed in people who belong to the age group of sixty years or above that.

Other than that it can also be caused due to hyperthyroidism, a condition where the thyroxine hormone from the gland present in the neck is produced in huge amount and thereby increase the metabolism of the body.

If a person is feeling difficulty in breathing, light in the head, fatigued, face difficulty in activities like exercising, feels weakness in the body or faints, then they must visit a doctor as these are some of the symptoms that are observed in a human body whenever he or she has atrial fibrillation.

However, atrial fibrillation can be treated and cured. One of the most effective treatments that are followed or prescribed by doctors is AV node ablation.

What is CHF?

CHF or congestive heart failure is a disorder related to the human heart which occurs when the heart doesn’t pump properly, resulting in the collection of fluids in the body.

People who have blood pressure issues, people who have a family history of congestive heart failure, people who have problems associated with heart valves, people who have coronary heart disease or have cardiomyopathy are more likely to get diagnosed with congestive heart failure.

If a person’s left ventricle of the heart is affected, then he or she can feel extremely weak and tired, can face difficulty in breathing and the cardio output is also reduced.

A patient can be cured by introducing some changes in his or her diet and lifestyle and by following medications. Other than that, the treatment options may vary depending on the severity of the disorder.

Main Differences Between AFIB and CHF

  1. One can get congestive heart failure if one has a family history of it. On the other hand, one can not get atrial fibrillation if one has a family history of it.
  2. Treatments to cure atrial fibrillation include AV node ablation. On the other hand, the treatments to cure congestive heart failure include a heart transplant if the severity is more, medications and changes in dietary schedule and lifestyle in general.
Difference Between AFIB and CHF


Both atrial fibrillation and congestive heart failure can be prevented if a person eats healthy and lives a healthy lifestyle.

They should take care of their mental and physical health as much as they can and should try to stay fitter and happier as they can.
